Well guys I traded for a 966 that someone has taken the original fuel tank off and replaced it with a smaller aftermarket one. I was wondering if one off a 1066 will bolt in so i will have more fuel capacity. The tractor also has an aftermarket turbo setup and I was wondering if they were any good. If they arn't any good then I was gonna put it back original. thanks jordan.

What are you doing with it? I am sort of old school - adding something like a turbo has to add stresses to an engine like that. If you don't need it I would be taking it off. That tractor runs right around 100 HP. It was a fairly big tractor in its day (that was not articulated). Most aren't used to their capacity any more because they aren't big enough and lack some of the creature comforts that we like today. That said, I would snatch up a good one in a heartbeat and gladly spend hours running it. They are good tractors.

Disc mowers take some guts, but it isn't a 12 footer or anything. I'd pull that turbo off and let it work really good. That engine is at its best when it works hard. The best thing about using an IH for a disk mower is that if it is a 1000 PTO mower you don't have to change the shaft to use it. I have spent my week this week swapping PTO shafts on the 4440 JD as the shredder and mower got swapped around numerous times.

jordan, Loose the aftermarket Turbo!!! 966s were factory Non-Turbo Tractors!. At 100 hp they were still under rated. A 966 has Moooore than enough hp to twist the drive shafts off of your Swather/Baler with out the turbo.
The One and Only thing a D414 does not like is extended Idle time, light shore work! A D414 will start slobbering oil out the Exhaust onto the Manifold. But a quick work out at High Idle pulling, doing real work and that will stop in short order.
My 966 is a Beast, HP out the Wa-Zoo and is just about Bullet-proof.
OBTW.... An IH 2350 loader was made for this tractor! Get one! Hope this helps!

You might want to leave the turbo on it. They probably have the injector pump fuel turned up as well. You take the turbo off and the motor won't burn all the fuel when the tractor is under load. That turbo will also help cool the valves. Most people that added a turbo to a 966 just found the parts off a 1066. M&W made a aftermarket set up for these tractors but I don't know how they differ from IH turbo setup. I don't understand why the smaller fuel tank. TRACTOR PULLERS use small tanks to lighten up the tractor.

Everybody is telling you to pull the hair dryer , but i will not and as long as it is NOT tweaked to much on the pump it will be fine as the turbo will give ya that little extra plus lugging power that they lack . A close friend has a 966 as his BIG tractor and a OLD 806 that is turboed and has been since 1968 and the 806 is set at 120 . The 966 had to get a pump rebuild and it was set stock at stock settings it WOULD NOT run the two row chopper and pull a loaded silage wagon up the hills in low third with the T/A pulled back . The 806 would eat the 966 for lunch . End up giving the 966 a couple turns on the screw so we could use it to chop with . My non turbo 806 will out pull a STOCk 966 Now as to WHY some bozo would remove the fuel tank i have no idea unless they were usen it as a PULLING tractor and cut the tank down to save weight and when there idea of being grand national champ with a 966 with a hair dryer did not work out the put it back to a somewhat stock FARM tractor and dumped it . But i have seen many 966's with a turbo and as long as you do not get nutty with fuel they do help.And beside unless you check part #'s how do you know what was done to it and what might have been changed before you got it.

966 has different head and different pistons then a 1066 and a few other small differences .Plus we do not know WHAT hairdryer is on this one , so with out #'s of the charger and manifold and head pistons pump settings pump timing best to leave alone as is as he could open up a huge can of worms.

OK let's clarify a few things here. Adding a turbo in and of itself does not add any stress to the machine. it will still only develop as much power as the load on it requires. even if you put a load on it, you only get (much) more power if you also increase fuel delivery!

No matter how much you increase the fuel, that is the max setting! the pump will only deliver the increased fuel if you put an increased load on it.

if for example you take a stock 806 that is set at 95 HP and put a turbo on, then set at 95 hp again, you will probably end up turning the pump DOWN, have cooler exh temps but still have the same torque at the flywheel at a given load.

Why the big deal about stress on the engine. You will buy a 1086 and it has the same engine in it pushing out about 135HP so no big deal. Just run it. The tank might have come from a junkyard off from a custom model. The full tank will only give you about 40-50 gallon so not much difference. Just use it. It will be fine like it is. I agree with Tractor Vet. Use and enjoy.
